MILK STRAINER.

No. 350,110. Patented 001;. 5, 1886.

I V/TNEEEEE um M N 7777 is one of the desiderata in liNiTEn STATES Parent @rriceo MILK-STRAINER.

Application tiled August 6, l-SS.

To aZZ whom, it may concern:

Beit knownthat I, ()LrvuR L. F. Bnowivu, of Syracuse, in the county of Onondaga, in the StateofNewYork, have invented newand useful Improvements in Milk-Strainers, of which. the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

Theobject of this invention is to filter liquids in such a manner as to obviate excessive agitation and the resultant disintegration or comminution of the impurities or foreign substances to be eliminated from the liquid, there by more effectuallypurifying the liquid. This the treatment of milk in dairies, and I have therefore adapted my invention more particularly for such uses, and the following description and the drawings hereto annexed describe and show myinvention in connection with dairy appliances; but I wish it to be distinctly understood that I do not limit my invention solely to such applications.

In the accompanying drawings, Figure I is a vertical section of my invention applied to a milk-pail. Fig. II is a vertical section of my invention embodied in a form resembling externally a common milk-strainer. Fig. 111 is a horizontal section on line :0 51 Fig. I; and Fig. IV is a detached inverted plan view of the conduit which conveys the milk from the trap or well to the disehargeopeuing ot the filtering apparatus.

Similar letters of reference indicate corresponding parts in all the figures.

For use on milk-pails, I construct my invention as follows: To the top of the pail A, I fit a cap, 0, which is formed with a basin, B, constituting the receptacle for the milk to be filtered, and the bottom of this basin is formed with a depression, (I, to serve as a trap or well. At or near the highest side of the said trap or well the bottom of the basin B is provided with a discharge o )ening or spout, I), by which it communicates with the interior of the milkpail A, as illustrated in Fig. I of the drawings.

0 represents a water-tight conduit, which is extended from the top of the trap c to the spout b, and has its receiving-mouth d on the under side of one end and lacing the top of ea l-"ZION forming part of Letters Patent No. 350,110, dated October 5, 1886.

Serial No. 173.715. (No model.)

the trap, and horizontally across said mouth is spanned a liltering-dia ihragm, c, which may consist either ot'line textile fabric or other suitable filtering material. Said diaphragm is se cured to anammlarflange, 11, around the mouth of the conduit by a band, 1, titted inside of said flange and binding the edges of the diaphragm between them. The diaphragm is thus removable l'or cleansing or renewing it when re quired. From the under side ot' the opposite end ot the conduit projects a spout, j, which is inserted removably in the spout I), hereinbefore described, and fits closely thereto to support the conduit 0.

3y reterring to Fig. Ill ol' the drawings it will be observed that the top of the conduit c forms a guard or shield, s, which nearly com pletely covers the trap (I, said guard or shield performing an important function. when milk.- ing into the basin 12', mounted. on the pail. A, as shown, the streams or jets of milk being therebyJ n-(vented 't'rom entering direct into the trap (I, and are compelled to flow at a moderate speed trom the bottom of the? basin into the trap, around the top thereol', thus obviating agitaliouol'the milk in the trap and guarding against disintegration or comminution. of the impurities which attend the use of the common open pail in milking. The comparative calm state of the milk allows the impurities or loreign substances to a greater or less extent to precipitate in the trap u, aml the filteriug-diapln-agm 0, together with the mod erate overflow ol'the milk from the trap through the diaphragm serves ett'eetually to arrest the escape of the finer particles of foreign sub stances on the under side of the ('liaphragm, and thus thoroughly filter the milk. The pu ritied milk passes through the conduit and en ters the pail through the spout in Fig. II of the drawings the recepiacl e B for the milk to be iiltercd is otthe .t'orm ot' the body of an ordinary milk-strainer. this 1cce[ lacle is provided with a discharge opening or spout, I), and over the bottom is supported the conduit 0, havingat one end a spout, entering the spout I), and at the opposite end a receiving-mouth on its under side, across spanned the filteringwlia The bottom portion of the said which mouth is phragm c.

The bottom of rcceptacle'up to the conduit 0 constitutes the trap a, from whence the milk rises through the filtering-diaphragm, and thence passes through the conduit and out through the spout thereof.

It will be observed that in each instance herein described and shown I filter the milk in an upward flow thereof, and provide underneath the filtering material a trap or well in which the milk is comparatively tranquil, to allow the heavier particles of foreign substances to settle out of reach of the pulverizing effect of the inflowing liquid, and the milk passes through the filtering material without undue pressure. This constitutes the salient feature of my invention, it insuring a thorough elimination of the impurities or foreign substances from the milk.

What I claim as my invention, and desire to secure by Letters Patent, is

1. A filtering apparatus comprising a receptacle for the substance to be filtered, a trap or well at the bottom of said receptacle, a filtering-diaphragm over the trap, and a conduit over the diaphragm and leading from the same, substantially as set forth and shown.

2. The combination of a liquid-receptacle formed with a trap at its bottom, a discharge opening at or near the top of the trap, a con.- duit extended from the top of the dischargeopening and having its mouth on its under side and facing the trap, and a filtering-diaphragm spanning the mouth of the conduit, substantially as described and shown.

In testimony whereof I haveherennto signed my name and affixed my seal, in the presence of two attesting witnesses, at Syracuse, in the county of Onondaga, in the State of New York, this 3d day of August, 1885.
